Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477682, here are decompositions:

13 + 31477669 = 31477682
79 + 31477603 = 31477682
139 + 31477543 = 31477682
199 + 31477483 = 31477682
283 + 31477399 = 31477682
331 + 31477351 = 31477682
541 + 31477141 = 31477682
571 + 31477111 = 31477682

Showing the first eight; more decompositions exist.
